Definitions

  • the present invention relates to a process for printing polyester, cellulose acetate, cellulose triacetate or polyamide and their mixtures containing textile materials with etchable or etchable disperse dyes according to the etching pressure or etching reserve printing process, in which an aqueous etching printing or etching reserve printing paste containing an amino reductone as an etchant, an aqueous Contains solution of a thickener and optionally an etch or etch reserve-resistant dispersion dye, is pattern-printed on the textile material and the textile material printed in this way is then fixed and washed out.
  • Etching printing is a process in which the dyes already on the textile material are partially or completely destroyed by chemicals.
  • Classic etching printing is based on real, finished dyeings on which an etching paste is printed.
  • the etchable background dyes are destroyed in the printed areas and white etching results.
  • the etching paste also contains etch-resistant dyes, the so-called illumination or colored dyes, a colored set is created.
  • a variant of classic etching printing is the etching reserve printing, in which the dyes to be destroyed sit on the fiber surface but are not yet fixed.
  • etching agents which contain, for example, a strongly alkaline compound or a reducing agent, such as tin-II salts, in particular tin-II-chloride, or derivatives of methanesulfinic acid , where alkali-cleavable or reducible dyes for the basic dyeing of the fiber materials to be printed are destroyed as completely as possible by the etchant, while alkali-resistant or irreducible dyes as illuminating dyes for colored effects (in contrast to white effects in the absence of illuminating dyes) to achieve patterns of any size with as much as possible not sharp contours on the fiber materials to be printed by the etchant be destroyed.
  • a strongly alkaline compound or a reducing agent such as tin-II salts, in particular tin-II-chloride, or derivatives of methanesulfinic acid

  • 3-amino reductones of the formula I are known compounds, for example they are described in European Patents 83 008 or 124 752. This prior art shows that they are suitable for stabilizing organic compounds or organic compositions against oxidative influences and that amino reductones can influence the growth of animals. It was by no means obvious and it was all the more surprising to find that such amino reductones can be used as advantageous etching agents under the conditions of the etching pressure or etching reserve printing process.
  • amino reductones of the formula I can be prepared, for example, exactly analogously to the processes described in European Patents 83 008 and 124 752, so that further explanations are not necessary.

  • the particular advantages of the amino reductones to be used in the printing pastes are the low application rate, the ease of degradation and the avoidance of heavy metals and stabilizers.
  • the development of formaldehyde when printing on the textile materials is avoided with the printing pastes according to the invention.
  • the amino reductones of the formula I are used in a manner known per se and known to the person skilled in the art in the form of printing pastes for the etching printing or etching reserve printing together with thickeners and, if appropriate, etching-resistant disperse dyes and the customary auxiliaries.
  • These printing pastes contain, based on the weight, 1 to 10% by weight, preferably 5 to 7% by weight, of an amino reductone of the formula I or its acid addition salt.
  • the textile goods are printed, e.g. Woven or knitted fabrics made of polyester, cellulose acetate, cellulose triacetate or polyamide or mixtures thereof. Textiles from the types of fibers mentioned are known. Disperse dyes are used almost exclusively as dyes.
  • the etching reserve printing process can be carried out, for example, by first padding the textile material with a liquor which contains an etchable disperse dye.
  • the textile material can also be printed with a printing paste which contains an etchable disperse dye together with a thickener.
  • the textile material is then dried under conditions such that the dyes are not yet fixed.
  • the textile is then printed with a mixture of an etch-resistant disperse dye and the etchant according to the invention and dried.
  • the dyes are then fixed, e.g. by thermosolating or heating the textile goods in a superheated steam atmosphere. Under these conditions, the etchable dye is destroyed at the locations on which the mixture of the etch-resistant dye and the etchant has been printed. This procedure is called the etching reserve because the base of the goods is colored, but the dye is not yet fixed.
  • a variant of the etching reserve method is that the mixture of etch-resistant dye and reducing agent is printed on the textile and immediately afterwards the etchable dye is overprinted over the entire surface and the material is then dried and the dyes are fixed.
  • an etchable dye that has already been fixed on the tissue is etched with the etchant mixture according to the pattern.
  • White etching is also possible in all process variants, ie in this case a printing paste is used which contains an etchant mixture but no dye.
  • the dyeing of polyester can be carried out using carriers as well as under high temperature conditions, e.g. Dyeing under pressure in an aqueous liquor at 120 ° C.
  • the reductive post-cleaning required for polyesters takes place after printing and fixing, i.e. The rear and the areas printed for illumination are reductively cleaned in one work step.
  • the advantage of the coloring is the better levelness of the background, which is particularly important if, due to the pattern, only a few small areas are to be etched.
  • Pre-dyeing gives qualitative advantages, especially for knitted fabrics and very light fabrics. Synthetic fibers made of acetate or polyamide or their mixtures are dyed at a temperature of 85 ° C.
  • disperse dyes are used almost exclusively for the process according to the invention. Suitable dyes of this type can be found in the Color Index.
  • Etchable disperse dyes are those that are decomposed by the etchant into products that generally should not interfere with the white background or the colorful illumination. These are primarily disperse dyes that are derived from azo dyes.
  • the etch-resistant dyes are mainly disperse dyes based on anthraquinone derivatives. They are resistant to the etchant.
